The shuttle feeler5, which, upon the sub-.

'stantial exhaustion of a bobbin, is operated by the transferring mechanism to. move 'downwardly, from the position shown. in

Fig. 1,-to the position shown in Fig. 2, to' feel for and indicate the .proper position of. the active shuttle 9, has in this instance mechanisms combined therewith, which are adapted to carry the filling thread toward the end of the feeler 5, totbe cut.

, The feeler arm 5 has'in this instance an ward the'frontfof the loom.

lever 13 has a stud 14, to which is pivotally connected one end of a rod or connector 15. The other end of'said rod 15 is connected to the end ofa stud or bolt, 16, which slides loosely in an elongated slot 5 in the end 5" of the feeler 5, whichend extends to- The boltor stud 16 has loosely pivoted thereon a knife plate 17, which is -provided with a stud 18, adapted to'moye lhoselyf'infthe slot 0 Through the travel o'f the stud 16 in the upwardly extending slot 5 leading out of the-slot 5., a 'quarter of a turn is imparted to the knife plate 17, as shown in Figs. 2

and 3.

The knifeplate 17 is provided. with a hook end 17, which is adapted, on the dowm V ward movement of said hook, to catch the filling thread 11' which passes from the shuttle to the woven fabric, and to carry the thread 11 into a slot 5*, which is open at its end, and toward a cutter blade 19, see Fig. 7, which in. this instance is secured to the end 5 on the shuttle feeler 5. Through the engagement of the cutter end 17-on the knife plate 17, with the cutter blade 19, the filling 11 which passes from the shuttle to the shuttle feeler 5 is cut.

A steel plate 20, preferably covered with felt-,or other suitable material 21, forms in this instance a holding or clamping device, to cooperatewith the knife plate .17, for the end of the filling thread 11, which leads from the wove nfabric to the cutter. The clamping plate 20 is secured upon a leather washer 22, and above the knife plate17, by a screw 23. a

, When the shuttle feeler 5, upon the substantial exhaustion of the filling on the bobbin in the active shuttle, is moved downwardly, the knife plate 17 is in the position shown in Fig. 2. The lever or arm 13 has in this: instance a projecting stud 24, which is moved in the path of and is engaged by a projecting plate 25. securedto the rear wall 8 of the shuttle box 8. The lay 7, as it moves forwardly, causes the arm l3,through .the projection 25, to operate and through the intermediate connections to the knife plate 17, causes said plate to operate. he movement of the plate 17 and the hook end 17' thereon, causes the filling thread 11 to becaught and carried into the open slot 5. The further movement of the lay causes the shuttle feeler 5 to. be engaged by the rear wall 8' of the shuttle box 8, and to be moved upwardly again. The lever 13 has a second stud 26, which moves into a curved slot 27 in an arm 27, which has its hub 27 secured on the stud 3, see Fig. 1. Through the curved slot 27, the-arm 13 is moved to the position shown in Fig. 1, which carries the knife plate 17 and consequently the filling 11, by the hook end 17' of said knife plate 17, to the cutter and the; clamping device above described. A.-helically coiled contraction spring 28, has one end connected to a pm 13' on the lever 13', and-its other end to a lug 4 on the arm 4, and acts to move backwardlv the lever 13 and the Knife plate 17 connected therewith, to the position shown in Fig. 2, after the feeler 5 has been moved downwardly again.
